## Which one, for what

### fal video models (B)

Good for: An agent or team that wants to compare or switch between Seedance, Kling, Veo, MiniMax, Wan and open-weights video models with one key and one queue contract.

Ahead on:
- Reliability, 77 against 35
- Schema & documentation, 89 against 48
- Agent ergonomics, 81 against 55
- Security & auth, 63 against 28
- Maintenance & community, 81 against 57
- Transparency & trust, 60 against 46

Watch for: Billing differs per model (per second by resolution, per second by audio, per 1,000 tokens), and Kling v3 Pro shows $0.14 on the pricing page against $0.112 or $0.168 on its model page

### Vidu API (E)

Good for: Batch jobs that can wait for off-peak prices and want reference-to-video or start-end frames with sound.

Also in its favour:
- Runs on your own machine

Watch for: No llms.txt, OpenAPI file or error-code reference

## Verdicts

**fal video models.** One key and one queue API reach 137 active text-to-video endpoints, each with a published price, an OpenAPI document and an llms.txt. Billing units, duration formats and audio pricing differ per model, there is no free tier, and a person must sign up in a browser and buy credit.

**Vidu API.** Q3 Turbo from $0.035 a second at 540p, about half that off-peak. No llms.txt, OpenAPI file or error-code reference.

## Before you call either

### fal video models

1. Submit to `queue.fal.run`, keep the `request_id`, then poll `status_url` or set `fal_webhook`. Never resubmit to check progress, because each submit is a new billable job
2. Read `https://fal.ai/models/<endpoint-id>/llms.txt` before a call. `duration` is the string `"5"` on Kling, `"8s"` on Veo 3.1 and an integer on Wan 3.0
3. Set `generate_audio` on purpose. It defaults to true and raises the Kling v3 Pro price from $0.112 to $0.168 a second and Veo 3.1 from $0.20 to $0.40
4. Check `metadata.status` in `https://api.fal.ai/v1/models` before pinning an endpoint. Deprecated endpoints carry no removal date
5. Use an API-scope key, never an ADMIN key. A new account runs 2 requests at once, so long video jobs queue behind each other
6. The MCP relay has no server-side approval gate. Call `get_pricing` and get the owner's approval before `submit_job`

### Vidu API

1. Send `Authorization: Token $VIDU_API_KEY`. The scheme is Token, not Bearer
2. POST the task, then poll the Get Creation endpoint by task id or set `callback_url`
3. Set `off_peak` only for jobs that can wait up to 48 hours. It roughly halves the credit rate
4. Set `audio` to true for dialogue and sound on Q3. It's off by default
5. Keep the AI-generated label on outputs. The terms forbid removing it
